| Abstract: | On the basis of the Upper Cambrian Changshanian trilobite succession in the Liaodong Peninsula, a new biostratigraphic scheme is foundeed. Six trilobite zones and two sub-zones are distinguished. These are as follows in descending order. 6. Kaolishania Zone5. Maladioidella Zone4. Eochuangia Zone3. Changshania Zone2. Chuangia Zone1. Prochuangia-Paracoosia Zone6. Kaolishania Zone: This zone is divisible into two subzones, the lower, Kaolishania granulosa Subzone and the upper, Kaolishnuia pustulosa Subzone.5. Maladioidella Zone : Enshia sp. , Irvingella major Ulrich et Resser, Maladioidella splendens En-do, Mansuyia planilimbata(Endo).4. Eochuangia Zone: Eochuangia hana Kobayashi, Paraqingshuiheella convexolimbata(Endo).3. Changshania Zone: Changshania conica Sun , Irvingella taitzuhoensis Lu, Parachangshania hsiaoshi-hensis Chien, Shirakiella suni Chu.2. Chuangia Zone: Chuangia batia(Walcott), Ch. conica Endo, Ch. transversalis Kobayashi, Dokimocephalus sinensis sp. nov. Homagnostus hoiformis (Kobayashi), H. turmdosus (Hall et Whitfield) , Maladioides asiaticus Kobayashi, Pagodia hemisheriaca Resser et Endo, Proceratopyge liao-tungensis Kobayashi et Ichikawa, Pseudagnostus ( Ps. ) chinensis (Dames) , Pseudosolenopleura kotoi (Kobayashi), Stigmatoa liaoningensis sp. nov. , Wanwainspis paichiaensis (Kobayashi), Metachangsha-nia striata(Lu et Qian), Yokusenia vulgaris Kobayashi, Y. lorenzi(Kobayashi).1. Prochuangia-Paracoosia Zone: Paracoosia deprati (Mansuy) , P. mansuyi Kobayashi, Parako-tuia convexa sp. nov. , Proceratopyge fenghwangensis Hsiang, Prochuangia mansuyi Kobayashi, Pr. quadriceps ( Dames ) , Pseudangnostus ( Ps. ) communis ( Hall et Whitfield ) , Ps. ( Ps. ) chinenesis (Dames), Ps. (Ps) idalis opik, Wuhuia minus(Endo), Yuepingia niobiformis Lu, Y. subconica sp. nov. |
